4 especially for watering hogs.

The primary object of'myinvention` is vto render the body of water in such a trough, automatically fed thereto vas the supplyl is used, anti-freezing in cold weather. To this end I` sink the body of the trough inthe between it and the normal water-level in the" trough at 10.l The cover is shorter in lengthl than the body. 4 to form an opening at one end of the latter, and a baiile A12 depends i from that end of the cover into the trough some distance below the water-level therein.-

The drinking space 1l thus; provided between the battle and adJaCent end of .the trough, is sufficiently large to permit the animals vto have easy access to the water;

and as the water' is withdrawnl by their drinking, the supply is automatically replenished by'the resultant sinking of the oat toA open the valve 6, which is again closed with the rise of the Water-level in returning the iioat to its normal valve-closing positiorr This drinking'space, however, is

ground to a depth that will raise its top but of such dimensions as to expose to. the

` slightly above the ground level and render it weather only a small surface-area of the accessible for drinking, and feed the waterbody of water in the trough but if the waby a pipe extending below the frosteline terat-that point were to freeze to any greatunderground through the bottom ofI the depth, or to a depth sulicient to prevent. the trough into the latter wherein it is equippedn anlmalsfrom getting water, the apparatus with a float-controlled shut-off valve; and-I. Would, obviously, be practically ineffective provide the trough with a' raisedcover, forming an air space between it and the waterlevel, the cover being 'shorter than-the trough and having a baffle de ending at its shorter end into the trough elow the water-level therein to leave a small opening between the `baii'ie and trough-end of -suchdimensions as y'to comfortably admit the snout for drink- In the accompanying drawing, Figurel 1 is a plan view of my improved watering trough; Fig. 2 isa section on line 2', Fig. 1, showing the trough in its operative, Asunken condition equipped with automatic feeding` means; and Fig. 3 is a section on line 3, Fig. 1.

The trough vbody 4 is shown of oblong rectangular shape, though it may be of other desired shape, and'be made of wood, concrete, or any other suitable material. In use the trough is sunk in the ground, asl represented in Figs. 2 and 3, and isfed with wa-v teruflrom a suitable overhead .or other, automatic pressure supply (not shown), through a pipe 5, buried, as to its horizontal length to a depth underground to which frost 'is not likely to penetrate and risingA into the trough through its bottom. The pipe is provided at itsupper end in the trough with a suitable valve 6 .controlled by a ioat 7. AA raised 'cover 8 seats on top of the walls f the trough body and forms an ample air space 9 ndprovid'ed with a depending wall or par-'- deep freezing, of the waten exposed at thedrinking opemng, and to prevent the freez.-

ing infiuence from extending thence into the 'body of water in the trough. In fact, in the 1use` of my trough, insulated 'as described, during the winter, exposed to a temperature of 20 F. below zero, a mere film of ice formedover the water-surface at the open- -v i ing 11;` and at 28 F..below zero the ice4 formed there to a thickness of only about one-fourth of an inch and was readily broken by the hogs in gaining access to the water.

l/Vhile my improvement is, primarily intended to prevent freezing of the body of water in the trough in ,cold weather, it' ob= viously, but with less pur ose, prevents the i water from becoming un u ly warm in the slimmer, because of the Vsmall area exposed at the drinking opening, and the attemperating influence of the'supply through the pipe 5 supplemented bythe confined air in the space 9. ,l
